Consider the following polynomial inequality.
x^2(x+5)(x−6)>0
Set one side equal to zero and list the interval endpoints (the only points at which the non-zero expression can change sign).
Separate multiple answers with a comma.
Answer:
Well, x^2(x+5)(x−6)>0= x<-5 or x>4
Step-by-step explanation:
Just have to simplify it as I can't type the equations right now.
The polynomial expression of inequality is x² ( x + 5 ) ( x - 6 ) > 0 is given by the values ( x < -5 ) and ( x > 6 )
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
x² ( x + 5 ) ( x - 6 ) > 0
So , the values of x that are greater than 0 is given by
x² > 0
So , the value of x > 0
when ( x + 5 ) > 0
Subtracting 5 on both sides , we get
x < -5
when ( x - 6 ) > 0
Adding 6 on both sides , we get
x > 6
So , the inequalities are ( x < -5 ) and ( x > 6 )
Hence , the polynomial inequality is solved

Work out the percentage change when a price of £10 is increased to £12.
Answer:
20%
Step-by-step explanation:
Use the percent change formula: difference = % * original cost
12 - 10 = 2
The difference is 2 and the original cost is 10. Now, we have the equation
2 = % * 10. We don’t know the percentage right? So now we have to find the percentage. To do this, you will have to do 2 divided by 10, which is 0.20. Lastly, we have to turn 0.20 into a percentage by multiplying it by 100, leaving you with 20%. So therefore, 20% is the percent increase. Hope this helps!

Answer:
1 - 58°
2 - 122°
3 - 58°
Step-by-step explanation:
Important notes:
• Vertical Angles Theorem - The angles that are opposite to each other on an intersection of 2 lines are always congruent.
• Linear Pair - The two angles that are formed when a straight line is split. Linear pairs are supplementary angles.
• Supplementary Angles - An angle pair whose total measure = 180°.
Angle 1 is supplementary to the angle with measure 122°.
So, ∡1 = 180 - 122.
∡1 = 58°
Based on the Vertical Angles Theorem, ∡1 ≅ ∡3, so ∡3 is also 58°.
Based on the Vertical Angles Theorem, ∡2 ≅ 122°, so ∡2 = 122°.
∡1 = 58°
∡2 = 122°
∡3 = 58°

On a trip, a student drove 42 miles per hour for 3 hours and then drove 26 miles per hour for 5 hours. What is the student’s average rate of speed, in miles per hour, for the whole trip
Answer:
34 mph Is correct answer
Step-by-step explanation:
Average speed = total distance / total time
Total distance = ( 40 × 2 + 30 × 3 )
= 170 miles
Total time = 5 h
So, avg speed = 170/5 = 34 mph

Stella needs to make at least 8 cakes for a bake sale. A chocolate cake requires 5 cups of flour, and a fruit cake requires 3 cups of flour. She has at most 120 cups of flour.
Which system of inequalities represent the number of chocolate cakes (c) and the number of fruit cakes (f) Stella can make?
A.
B.
C.
D.
Answer:
A. c + f > 8
5c + 3f < 120
Step-by-step explanation:
Let c = chocolate cakes
Let f = fruit cakes
She must make at least 8 cakes
c+f ≥8
A chocolate cake requires 5 cups of flour, and a fruit cake requires 3 cups of flour and she has only 120 cups of flour
5c+3f ≤120
The two equations are
c+f ≥8
5c+3f ≤120

The base of a triangle is 4 inches more than 3 times the height. If the area of the triangle is 66 square inches, find the base and height.
Answer:
base = b = 11
height = h = 2
Step-by-step explanation:
.5 * b * h = 11
.5 * (4h + 3) * h = 11
(4h + 3) * h = 22
4h2 + 3h = 22
4h2 + 3h - 22 = 0
(4h + 11) (h - 2) = 0
h = -11/4 OR h = 2

The path of a skateboarder can be modeled by the equation (x – 4)2 = –4(y – 9), where distance is in feet and air resistance is insignificant. If the skateboarder makes a jump from a ramp at x = 0, what is her maximum height and how far is she horizontally from the end of the ramp when she lands?
Maximum height 4 feet; horizontal distance 12 feet
Maximum height 5 feet; horizontal distance 10 feet
Maximum height 9 feet; horizontal distance 12 feet
Maximum height 9 feet; horizontal distance 10 feet
Answer:
Maximum height 9 feet; horizontal distance 10 feet
Step-by-step explanation:
First, let's get the distance out of they way
When the skateboard lands, her height will be at 0 feet, so y has to equal 0
(x - 4)² = -4(0 - 9)
(x - 4)² = -4(-9)
(x - 4)² = 36
Square root both sides
√(x - 4)² = √36
x - 4 = 6
Note that x - 4 = -6 is also possible
Add 4 to both sides
x - 4 = 6
+ 4 + 4
x = 10
Note that x = -2 is also an answer. but not valid
To find the max height
Remember our zeros? x = -2, x = 10
The number in the middle would be 4
Plug 4 in place of the x in the original equation
(4 - 4)² = -4(y - 9)
(0)² = -4(y - 9)
0 = -4(y - 9)
You can divide both sides by 4
0/4 = (-4(y - 9))/4
0 = y - 9
+ 9 + 9
y = 9
Vertex is (4,9); or in other words, 9 feet is the max height

Solving systems of equations by substitution 2x - 3y = 19
x - 2y = 11
Answer:
[tex]\boxed {\boxed {\sf (5, -3)}}[/tex]
Step-by-step explanation:
We are asked to solve the system of equations by substitution. We must isolate a variable and plug it into the other equation.
We are given these 2 equations;
[tex]2x-3y=19[/tex]
[tex]x-2y=11[/tex]
1. Isolate a Variable
We can easily isolate x in the 2nd equation. 2y is being subtracted from x. The inverse operation of subtraction is addition. Add 2y to both sides of the equation.
[tex]x-2y+2y=11 +2y \\x= 11+2y[/tex]
2. Substitute and Solve for y
x is equal to 11 + 2y, so we can substitute this expression in for x in the 1st equation.
[tex]2x-3y=19[/tex]
[tex]2(11+2y)-3y=19[/tex]
Now we can solve for y by isolating the variable First, distribute the 2. Multiply each term in parentheses by 2.
[tex](2*11) + (2*2y) -3y = 19[/tex]
[tex]22 + 4y-3y = 19[/tex]
Combine the like terms.
[tex]22+y=19[/tex]
22 is being added to y. The inverse operation of addition is subtraction. Subtract 22 from both sides of the equation.
[tex]22-22+y=19-22\\y= 19-22 \\y= -3[/tex]
3. Solve for x
We know that y is equal to -3, so we can plug it back into either original equation and solve for x. Let's use the 2nd equation.
[tex]x-2y=11[/tex]
[tex]x-2(-3)=11[/tex]
Multiply -2 and -3.
[tex]x+6=11[/tex]
6 is being added to x. The inverse operation of addition is subtraction. Subtract 6 from both sides of the equation.
[tex]x+6-6=11-6\\x=11-6 \\x=5[/tex]
We found that y=-3 and x=5. Coordinate points are written as (x,y), so the solution for this system of equations is (5, -3).
